COMPUTED-TOMOGRAPHY AND NEUROLOGICAL SOFT SIGNS IN OBSESSIVE-COMPULSIVE DISORDER

Computed tomography was used to compare the following three groups: ob sessive-compulsive disorder (OCD) patients with high scores on a soft neurological sign examination, OCD patients with low soft neurological sign scores, and control subjects. Neuroanatomical structures were me asured using quantitative volumetric analysis. OCD patients with high soft sign scores had significantly increased ventricular volumes compa red with OCD patients with low soft sign scores and control subjects. Caudate and lenticular nucleus volumes did not differ between groups.
